Does the stepper motor need a reducer? What's the function of the plus and minus speed machine?
Stepper motor and reducer only objective is to increase the torque about low speed stepping itself is about more Gaonajia the precision of low-speed motor reducer to only in order to increase the output torque of the motor with precision reducer.
Reducer in the prime mover and working machine or actuator between the matching speed and torque transfer role, reducer is a relatively precise machine, the purpose of using it is to reduce speed, increase torque. According to transmission series can be divided into single and multi-stage reducer; gear wheel factory according to the shape can be divided into cylindrical gear reducer, bevel gear reducer and bevel gear-cylindrical gear guide wheel reducer; according to the arrangement of transmission can be divided into expansion, split and same shaft type speed reducer. The reducer is a kind of independent parts enclosed by a rigid shell gear, worm gear, gear - worm gear reducer, commonly used as a prime mover and work machine. It plays an important role in matching speed and transmitting torque between prime mover and working machine or actuator, and it is widely used in modern machinery.
Look at the torque required. If the gear is out of range, the only purpose is to increase the torque.2, stepper motor is to change the electrical pulse signal to angular displacement or linear displacement of the open-loop control element stepper motor. In the case of non overloaded, the motor speed and stop position depends only on the pulse frequency and pulse number, regardless of load changes, when the stepper driver receives a pulse signal, it drives stepper motor to set the direction of rotation of a fixed angle, called "step", it is the rotation of the fixed point of the operation step by step. Number of pulses can be controlled by controlling the angular displacement, so as to achieve the purpose of accurate positioning; at the same time by controlling the pulse frequency to control the motor rotation speed and acceleration, so as to achieve the purpose of speed.
